Answer:

1. 8x + 3y - x - 2y

= 8x - x + 3y - 2y

= 7x + y

2. 3n - 7n - 2n + x + 8x

= 3n - 9n + 9x

= - 6n + 9x

3. 2r - 5n + 9y - 3r + n

= 2r - 3r - 5n + n + 9y

= -r - 4n + 9y

4. 12y - 6x + 5y - 3n

= 12y + 5y - 6x - 3n

= 17y - 9n

5. - 13n + 4n - r

= -9n - r

6. 7xy - 8x + 6xy - y

= 7xy + 6xy - 8x - y

= 13xy - 8x - y

7. - 14r - 10n - 3r - 9n

= -14r - 3r - 10n - 9n

= - 17r - 19n

8. 6r + 9r - 2r - 13n

= 6r + 7r - 13n

= 13r - 13n

9. n + r + x - 3x +4r

= n + r + 4r + x - 3x

= n + 5r - 2x

10. 15y - 7x + 9z + 4z - 3x

= 15y - 7x - 3x + 9z + 4z

= 15y - 10x + 13z

Will mark brainliest if correct.

Answers

As we know y=3/4x-3
Let's put it in the second equation
3/4x-3=1/4x+1
3/4 x -1/4 x = 1+3
2/4 x = 4
X= 4*4/2
x=8
Put x= 8 in first equation
y= 3/4 *8 -3
y=6-3
y=3
Check the answer
3=3/4 *8 -3
3=6-3
3=3
Correct
So(y, x) = (3,8)
Because x=8 and y=3

I need help please, If triangle JKL is congruent to QRS, find each missing value

Answers

Answer:

x = 5, y = 17, z = 8

Step-by-step explanation:

   Since the triangles are congruent to each other, corresponding angles and sides are congruent to each other.

JL corresponds with QS so...

3x - 1 = 14

3x = 15

x = 5

RS corresponds with LK so...

y + 10 = 27

y = 17

Angle L corresponds with angle S so...

Answer:

B(-2, -5)

Step-by-step explanation:

Points given:

M(-5, 0) - midpoint A( -8, 5) - endpoint B(x, y) - endpoint

Use midpoint formula to find the coordinates of B:

x = (x1 + x2)/2, y = (y1+ y2)/2

Substitute known values and solve for x and y:

-5 = (-8 + x)/2 ⇒ -10 = -8 + x ⇒ x = -10 + 8 ⇒ x = -2 0 = (5 + y)/2 ⇒ 0 = 5 + y ⇒ y = 0 - 5 ⇒ y = -5

Point B is:
